I'm looking for a very small, around 3" long LED flashlight that uses AAA or AA batteries. I want to be able to put it on my keychain and it needs to be water resistant. It can't cost any more than $40. I looked through reviews from Flashlight Reviews and the LED Museum and the perfect flashlight seems to be the Arc AAA; however, they no longer make it and it's too expensive on ebay. I've settled on probably one from Peak LED Solutions, probably the Matterhorn AAA. Does anyone own one of these or used it? What is your opinion on it and can you guys recommend other good quality flashlights that meet my criteria??
